Dynamite glycerine

Since 1920, the price of refined glycerol in the United States has varied from a low of 0.22/kg in the early 1930s to a high of nearly 1.95/kg in 1987. In 1992 glycerin prices for USP grade ranged from 1.28 to 1.65 /kg. Since glycerol is a by-product of fatty acid, ester, and alcohol production, prices are quite sensitive to changes in oleochemical demand. Glycerol prices also respond to prices for tallow, coconut oil, and petroleum, the feedstocks from which it is prepared.  [c.349]
